Normalized steady-state (i.e., all ages) pitch-angle distribution for 81 keV electrons with λ_∥ = 0.1 AU (top), λ_∥ = 0.5 AU (middle), and λ_∥ = 1 AU (bottom). The constant Knudsen predictions from a simple Fokker-Planck model are plotted as well (Zaslavsky et al. 2024), with the Knudsen numbers K = 0.11 (top), K = 0.54 (middle), and K = 1.08 (bottom) computed from the model values at 1 AU (see Table 1).
